The invention provides a variable-thickness automobile front bumper and a manufacturing method thereof. The automobile front bumper comprises a front bumper body which is of a thin-wall structure. The front bumper body sequentially comprises a left body section, a left transition section, a right body section, a right transition section and a right body section. A left energy absorption box and a right energy absorption box are arranged on the inner side faces of the left body section and the right body section of the front bumper body respectively, so that the front bumper body is connected with an automobile front longitudinal beam. The left body section and the right body section are of a uniform-thickness structure. The left transition section and the right transition section are of a continuous variable-thickness structure and become thinner gradually from the two ends to the middle body section. The middle body section is of a uniform-thickness structure and is the thinnest portion of the whole front bumper body. According to the variable-thickness automobile front bumper, by means of the design of parts of different thicknesses, the requirement for collision safety of the automobile front bumper is met, and the design of light parts can be achieved at the same time.
